Abstract

The invention provides an electrical coupling device. The coupling includes a contactor device and a plurality of electrical contacts which close an electrical circuit between the contactor device and an adaptor device when the adaptor device is brought into physical contact with the contactor device, there being no need for aligning for the electrical contacts of the contactor device with electrical contact of the adaptor device.

Claims

1. A coupling system comprising:

a first surface including a first set of contacts wherein at least two of the first set of contacts are arranged in a first predetermined pattern with respect to an orthogonal axes; and

a second surface including a second set of contacts wherein at least two of the second set of contacts are arranged in a second predetermined pattern such that when one of the first contacts and one of the second contacts are electrically contacted, another one of the first contacts and another one of the second contacts are electrically contacted without regard to the first and second surfaces being aligned with respect to the orthogonal axes.

2. A coupling system according to claim 1, wherein said first surface is substantially planar.

3. A coupling system according to claim 1, further including a load operatively coupled to said second surface.

4. A coupling system according to claim 3, wherein said load comprises an energy storage device.

5. A coupling system according to claim 4, wherein said energy storage device comprises a battery.

6. A coupling system according to claim 1, further including a power source operatively coupled to said first surface.

7. A coupling system according to claim 1, further including a sensor arranged to sense electrical contact between the one of the first contacts and the one of the second contacts and between the another ones of the first and second contacts.

8. A coupling system according to claim 7, wherein said sensor is arranged to sense a location of the first contacts and the one of the second contacts and between the another ones of the first and second contacts.

9. A coupling system according to claim 7, wherein said sensor is arranged to connect power to the electrically contacted contacts.

10. A coupling system according to claim 7, wherein said load includes an identifier having at least one parameter, and wherein said sensor is further arranged to sense the at least one parameter.

11. A coupling system according to claim 10, wherein said sensor is further arranged to connect power to the electrically contacted contacts in accordance with the at least one parameter.

12. A coupling system according to claim 1, wherein the first contacts and the one of the second contacts, and the another one of the first contacts and the another one of the second contacts are coupled to pass data.

13. A coupling system according to claim 12, wherein the data includes at least one of identification, product type, manufacturer, and polarity power requirements.
